Remove the LmxProxy work package (WP-8) from phase-3b, the CD-DCL-1..6
protocol details, Q9/Q-P3B-2 from the questions log, the LmxProxy
component-design rows in requirements-traceability, and the inline
mentions across phase-0, phase-4, the gRPC streaming plans, and the
primary/backup data-connection plans.
Organize documentation by moving requirements (HighLevelReqs, Component-*,
lmxproxy_protocol) to docs/requirements/ and test infrastructure docs to
docs/test_infra/. Updates all cross-references in README, CLAUDE.md,
infra/README, component docs, and 23 plan files.
All phases (0-8) now have detailed implementation plans with:
- Bullet-level requirement extraction from HighLevelReqs sections
- Design constraint traceability (KDD + Component Design)
- Work packages with acceptance criteria mapped to every requirement
- Split-section ownership verified across phases
- Orphan checks (forward, reverse, negative) all passing
- Codex MCP (gpt-5.4) external verification completed per phase
Total: 7,549 lines across 11 plan documents, ~160 work packages,
~400 requirements traced, ~25 open questions logged for follow-up.
